SPL & SQ / Fabrication

I was simply wondering what is some of the different types of Building Material are the best? I know the word best is subjective, but in this scenerio, weight is not an issue. Of course, I could simply double up on 3/4 MDF, and do some well bracing, I'm aware of that. But I'm also aware that, the material your using can greatly alter the output. Thats the main reason extreme vehicles use concrete. I am not willing to use concrete. I know I said weight is not an issue, but thats a bit much, plus would put me into the extreme class. The reason I'm asking, is because this will be my burp enclosure. I've heard of some competitors using marble, and other hard/rock like materia…

15" Xcon .... Was thinking about going sealed but then the idea of aero ports was brought up and I saw Stef's and loved the look and thought ... "Hey, a sealed enclosure is just a big box.. and a ported with aeros is just some tubing thrown inside of it and cut to the right length for tuning... I can do that.." Should I just do this? I was looking at PrecisionSoundProducts and said I could do this... Not much more work that building a sealed enclosure... Right??? So I looked up on their site for ports calculations and realized after understanding it a bit better that the Torres calculator does it as well... Here is what I come up with and it seem correct... Let me know wh…

Okay, So to find out what Hz my car peaks at, do I try out different test tones to see which one is the loudest in my car? If so, then what do I do from there? Say my car peaks at 37hz...do I tuned my port to 37hz? Reason asking is because I built a 2.5cuft. net @ 32hz enclosure with a 4" aeroport. I can take it out and cut it down for SPL. I just want to do it right since I only have one tube insert left. I'm aiming for SPL, not a fartbox. Thanks!

Hey guys! This is my first post on this forum, so please excuse me if I'm breaking any protocol. Anywho, if anyone's interested in Digital Designs' new T series subs, check out the link below in which I posted my build thread. I realize it's linked to Elemental Designs, but that's only because I was initially considering the use of their 8" sub. I can't compare the two, but let's just say that I am THRILLED with the performance, sound, and appearance of DD's T1508. I couldn't ask for anything more... well not from an 8" sub. Don't take that the wrong way, though. If I were to compare to anything at the local Best Buy, I'd have to be looking at a single 12" or a pair of 10…

Does anybody run bandpass boxes and if so, what subs are good to run in that type of enclosure? I quit running bandpass boxes awhile back because I thought they hold in wayyyy to much sound....

Hey everyone. What do you think would be the best for music and spl box size for a 15" Zcon. Been looking but can't find the suggested box sizes on here. Thanks guys.

Hey guys, I am asking for as much input here as I can get. I have everything I need...it's sunny outside..but I am at a hault. OK, I take it back... my HO alt from Iraggi was attempt delivery so i cant pick it up till tomorrow, my 4 AP30001D's should be here any day, my 50 foot spool of 0 gauge, a 40 pack of 0 gauge terminal rings...and Kicker should be shipping back two 4 channels soon as well. Otherwise, i have the van, I have the subs, I have the 3rd 4 channel, 3 AGM batteries..same as Deka Intimidator..I got lots of wood... 2"x6"x8' boards for bracing... gonna make X's inside of squares..should be solid.

Still looking for a new car. One that I can also have a good daily SQ setup, even have room to compete in. I am also thinking on competing in SPL next year. I wish I could make up my damn mind. '99-current Lexus GS300 maybe IS. Still researching the difference '99-current 4-runner '99-current Accord '99-current Camery "99-current Maxima All these fit into my size, power, and gas milage requirements. I have drove all but the lexus. Sometime this wekend Ill drive one. I have a potential buyer on the ATV so I will have a decent down payment. But I wm looking for the best stock stereo placement and the car with the mose room for growth. Ideas and suggestions definatl…

I am looking for someone to build a enclosure for my 15" ssa xcon. It needs to be 4 cubic feet tuned to 29hz, i'd like a flared slot port, in a standard rectangular enclosure with dark charcoal carpet, with a rectangular 10" window on the top showing off the insides (which means the insides need to look nice to enough to show off), so what would this run??? any offers? Also to add I would like it to only be 16" in height and no more than 35" in width, and I would like it if you could let me know what the end result on the depth would be?

i did a 149.0db Sunday with 1 sub ported to 36Hz going to build an SPL box for it now and get over the 150.0db mark with a singel sub Jacob i am out of Flyers need more as everyone is wanting info SounsStream 15"XxX

After watching YouTube and attending a few myself. It appears competitions make the hobby kind of sour. Online were all friends, then comp day rolls around and it's like the wild wild west. I've seen a lot of friends and drama start and end from these "comps" Almost to the point I don't even like attending them. I go to shows to talk interact and enjoy the hobby. I just feel like comps get way too serious. FTLOB!!!!

What all do I need to model my zcon for the new enclosure? About to start building and want to have the enclosure design as good as I can.

http://www.woofersetc.com/index.cfm?fuseac...Product_ID=5091 I saw this on ROE and couldn't beleive the price! Are these like last years version of the 61i that is currently on the CDT "gold" web site. I remember old CDT eurosport, and only heard them once, I was pretty impressed but it was a 3 way. I just don't have that kind of cash ATM, and won't for a while with all the rest on my build up. Bump if anyone has experience with these? I might jump on this and let the H/U issue wait.. if these are a value anyone want to borrow me another 300 bucks so I can get 2 sets I would hate to miss out on sucha pwn sauce deal if these are in fact good?? lol I'm looking for some…

i still dont understand how they work and what the diff is... you got these kind with a bunch of little wires and a crapload of windings and youve got these: with a little bit of windings and thicker wire. is one better than the other? i dont understand.

My shop teacher has a 1 inch thick piece of plexiglass, and he said if I can find way to cut it, I can have it. I have a tablesaw, circularsaw, router, and a jigsaw, but wasn't sure if any of them would cut it. Will they?

OK, so I am hoping that some box building gurus can help me stop pulling may hair out trying to decide on what box design and subwoofer choice I should go with. As you know, the Toyota MR2 is a very small car with not much room behind its only 2 seats. It is mid engine, so the trunk in the back is of no use to me for subs. they must go right behind the seats in a wedge style box. Here is an MR2 and a pic of the space behind the seats: So I listen to all kinds of music literally, well maybe not country so much, but lots of stuff. I want it to sound musically nice but definitely want to produce as much SPL or should I say """SQL""" as possible if s…

I'm going to be building a small aero ported box for a friend soon, but he doesn't want to spend the extra few dollars to buy real aero's. He wants to go with just straight PVC pipe instead. Yes, I explained port noise and the advantages of having flared ports. Anyway, what's the best way to mount PVC pipe externally on a box? There's no flare to screw into the wood, only a straight pipe to sit inside the cutout. I'm having trouble trying to figure out the most stable and secure way of attaching the PVC. Thoughts?

Well I got a couple more 15" Rockford Fosgate RFR2215 Power DVC subs.. now I am ready to do my four 15's setup. At Slamology I got a 148.1 in DB Drag with 2 15's and 2 12's at 44hz. My goal with this new box build with four 15's is to hit 150db mark. I recently just started playing with Bass Box Pro and Google Sketchup and I have come up with a Design in Bass Box Pro and then tried to Model it the best I could in Google Sketchup so here it is. This will be powered by a T40001bd. 12 cubes after sub,port,bracing displacement with 1" MDF 4 6" PVC Ports 10.5" Long to get a tune at 38.01hz There will be a total of 9 1" Dowel rods for bracing in the box 4 from top to bottom 3…

Thanks in advance for the help. Alright I am planning on getting a 12" Fi Q D2 and already ordered a sundown SAZ-1000D to power it. I've never built a box before and I dont trust the audio shop here. I want to build a L shaped ported box. Its going in a 1997 chevy blazer so I have room. First should I go sub up port back or sub back port back? What are the benefits of each keep in mind I'm not going for spl. According to Fi "Ported box we recommend using 1.8-2.5 cubic feet @ 28-33Hz (I personally think that a 32hz tuning is optimal, and has the most output and is still the most musical daily driving). Use 12-16 square inches of vent area per cubic foot of volume." So I…

The Box design i used from a guy from SMD didnt pan out so well, i honestly think the port length was longer than in my plan.... It sounds like it tuned to 42hz instead of 32hz. That being said im hoping SSA forum can help!! Keep in mind id really like to keep the box either as wide and shallow or flat/wide/deep as possible. Basically im trying to fit the golf clubs in the back, either in front of the box, or on top. 12" Fi Q on ~1600RMS tuned to 30ish hz. thanks for the help fellas/ladies

Hey, I am looking to build an enclosure for one Sundown E-12 in the near future. I plan on putting it into a 2.5 cubic foot enclosure. (PWK recommends an enclosure for the E-12 of at least 60L (~2.1 cu ft) for a more linear response) I also want to use a 4" aeroport (precision port) 10.25 inches long for a tuning of 32 Hz. I think my question is, would it be alright to tune this box to 30 Hz? All it would require is 12 of port length compared to the ten and a quarter. I'm just slightly confused because I have heard not to tune too far below a subs res. freq. because it might cause roll-off right at the tuning. If it sounds stupid, that's because I read it once somewhere o…

when setting your gains on amps why cant you turn them all the way up. and if you have them less then half way are you still getting the rated power of the amp. say if the amp is 1000w RMS are you getting that no matter what the gains are set too..... jamie

Anyone know of of a snug fitting dual sub box that'll fit in back of the second seats? Im taking out far back seats want to leave middle seats. Only wanting to do dual 15" subs. Should they be enclosed also?
